IMPRVEMENT IN HACKLINGJVIACHINES.

Specification forming part of Letters Patent No. 128,647, dated July 2, 1872.

To allpersons to whom these presents may come:

Be it known that I, WILLIAM MONTGOM- ERY, of West Roxbury, of the county of Norfolk and State of Massachusetts, have invented a new and useful Machine for Beating J nte-Butts or other like brous matters; and* do hereby declare the same to be fully described in the following specification, and represented in the' accompanying drawing, of which- Figure 1 is atop view, Fig. 2 a side elevatiOn, and Fig. 3 a longitudinal section, Of such machine.

` In such drawing, A denotes a cylindrical case or drum, provided with rectangular openings a b at top and bottom, and another Opening, s, between the two. An air-distributer,

I, or metallic plate perforated with numerous holes, is fixed in the opening a; and to the opening b there is a curved door, d', which is hinged to the side of the opening. Thecase so made is fixed within a frame, B, and opens one being disposed between those of the other,

so as to enable the cylinder to readily revolve within the case. On the arbor or shaft e of the cylinder are three pulleys, f g h, one of which, f, is a loose pulley, and the Others fastpulleys The pulley g serves to drive the cylinder by means of an endless belt from `a suitable motor, drum, or pulley. On the shaft of the lower feed-roller are two pulleys, i k, one of which-viz., the pulley'z'-is fast7 and the other loose on the shaft, and is connected with the pulley h by an endless crossed belt, l. A clutch, m, provided with an operative lever, n, and arranged to slide on the shaft of the said lower feedroller, serves to engage the shaft with the pulley la, as circumstances may require. Furthermore, an endless belt is to go about the pulley i, and another pulley, x, fixed On the shaft of the rear roller ,for supporting the endless apron. Theidoor at the bottom of the case is pivoted to two levers, o o', which are connected by a cross-bar, p, pivoted to a pedal Or hand-lever, r, all being arranged in the frame as shown, and applied together 'in a manner to enable a person, by means of the pedal 1', to either open or close the door.v

The purpose of the perforated plate at the upper part Of the case is to allow air to enter the case in numerous currents, and to bedistributed equally upon the cylinder, in Order to prevent the jute from becoming drawn between the ends Of the cylinder and those of the case, as it will without the air-distributer. .It also serves to supply air to the case during discharge Of the beaten material therefrom.

In using the machine an attendant, standing in rear of the endless apron, places and spreads upon it while it may be in motion a quantity of the jute-butts; and he is to continue to supply it with such as fast as may be necessary. At the proper time he is to seize the clutch-lever and move the clutch, so as to cause the feed-rollers to revolve and take up the butts and feedv them into the case. The

ltoothed cylinder being in rapid revolution,

will catch the brous material and draw and beat it against the teeth of the case so as to separate from the fibers the bark and other extraneous matters. After the cylinder may haverevolved a sufiicienttime to produce the desired result the door of the case is to be opened. The cylinder continuing to revolve rapidly, a stron g current of air will be drawn through the air-distributer into the case, andv various machines.

What I claim as my invention is- The machine, as described, composed of the feed-apron E and rolls C D, the toothed cylinder H and case A, the air-distributer I and the door d', all arranged and constructed substantially in manner, and provided with mechanism for operating them, as explained.
